How to Do Your Own Faucet Repair

If your faucet leaks around the handle, it can be repaired with a basic cartridge-style repair kit. Use a pocket knife to pry off the index cover and expose an Allen screw, then loosen it with a hex wrench.Faucet Repair

Shut off the water supply and remove the handle by unscrewing a tiny screw underneath each knob (some are seized, so use penetrating oil if necessary). Disassemble the faucet, then replace parts according to type. Visit to learn more.

Cartridge faucets tend to last a long time but can develop leaks that require cartridge replacement. While many people consider hiring a professional plumber to perform this task, it is a fairly simple job that can save the cost of buying and installing a new faucet. You can find kits with all the parts you need to do a faucet repair at most home centers and hardware stores. These include all the valve seats and springs you’ll need to replace the existing ones. Some kits also contain a replacement cartridge, although it is possible to purchase one separately from any home improvement center. Before you begin working on your faucet, shut off the water supply to it by turning the valve under the sink counterclockwise.

You’ll need a set of pliers, a wrench or adjustable pliers and a screwdriver to remove the handle from the faucet body. Duct tape the jaws of your slip-joint pliers to protect them and any other components on the faucet from damage as you work. You’ll need to remove the decorative cap from the handle and unscrew the set screw or Phillips screw, depending on your faucet type. Then tilt the handle back to pull it off.

Once you have the handles off, remove the bonnet nut from the faucet cartridge by loosening it with your wrench. You may need to wiggle the stem a bit to get it to come out. Once the cartridge is removed, you’ll need to replace any worn parts. Make sure to clean the mineral deposit buildup off of all faucet parts before replacing them. It’s a good idea to label the parts that go where so you can reassemble the faucet correctly.

To install a new cartridge, first insert it into the faucet body and ensure that any tabs on the cartridge are lined up with the retaining clip notches. Then firmly push the cartridge in until it’s fully seated. If there is a retaining clip, it might need to be twisted with your plastic spanner tool or pliers in order to line up with the notches or slots.


The ball-type faucet has a control ball that is open or closed to direct hot and cold water to the spout. The inlet holes are sealed with valve seats and pressed tight against the control ball by springs. If the inlet seat or springs are worn, leaking may occur. You can replace these parts to fix the leaky faucet. These are usually readily available at a hardware store, although a plumber’s supply shop might carry the specific model you have.

Turn off the water at the stop valves under the sink or at the main water valve to prevent spills and damage to other parts of the plumbing system. Plug the sink drain to keep small parts from falling into the sink during the repair process. Remove the handle and decorative cap from the faucet. Detach the set screw with an Allen wrench found on the underside of the handle. Set the screw aside. Remove the dome assembly and handle adapter to expose the handle stem. Detach the stem by loosening a slotted nut with a wrench or hex tool hidden underneath.

Use slip-joint pliers to loosen and lift the dome assembly to expose the bonnet, cam and ball. Remove the plastic cam and ball with needle-nose pliers. Inspect the ball for signs of cracking and sediment build-up. If it is cracked or damaged, a plumber can replace it. Using a flat-head screwdriver, remove the rubber valve seals and springs from the inlet ports inside the faucet body. Make note of how the springs are oriented so you can replace them with a new set correctly.

Obtain a replacement for the faulty part at your local home center or hardware store. A repair kit will usually include the new O-rings, springs and valve seats that you need to fix the leaky faucet. Be sure the kit is designed for your specific brand and model of faucet.

Ceramic disc faucets are a modern development that eliminate the need for springs, rubber seals or aerators. Their self-contained cartridge holds two ceramic disks with opposing triangular cutouts. When the lever is raised, the openings are aligned to allow water flow through the valve. When the lever is lowered, the openings are closed and water stops flowing. This system is more reliable than other faucets and requires less maintenance. However, the ceramic disks can develop cracks or discolor from mineral buildup over time. In most cases, a simple cleaning will restore the faucet to normal operation.

Unlike rubber seals, the disc assembly is made of a long-lasting ceramic material that does not wear out easily. The tiny crevices of the discs can become clogged with sediment, and the lubricating grease inside the cartridge base may need replacing. If a ceramic disc faucet begins to leak, it is likely due to a damaged O-ring.

To replace a ceramic disc, first shut off the water supply. Locate the hot and cold water shut off valves under the sink. Turn the valves clockwise to shut off the water. Next, remove the cartridge and replace it with a new one. After reassembling the faucet, test it for leaks.

If the replacement disc does not fix your fountain, you can purchase a kit that includes a special tool to remove the old disc. This is a very inexpensive alternative to buying a brand-new faucet. The kit also includes a replacement face seal that fits over the cartridge.

A leaking faucet is more than just a nuisance. If left unattended, it can lead to mold and mildew. In addition, the water that is leaking from the spout can damage your floors and ceilings. It is important to repair a leaky faucet as soon as possible to avoid costly repairs.

A leaking faucet can be very frustrating, but the repair process is relatively easy. First, you must close the drain and plug it with a towel. You can then release the water pressure by turning on the handle as far as it will go. After that, you can remove the spout and aerator. After that, you can unscrew the set screw and pull out the cylinder. Then, you can replace the cylinder with the new disc and put everything back together.

Repairing a leaky faucet

If your leaking faucet is a cartridge style, you can usually fix it with a few easy steps. This will save you the expense of a plumber and the potential damage caused by uncontrollable spraying water. The first step is to shut off the water supply valve under the sink. Doing this will prevent any accidental flooding of your home while you work on the leaky faucet.

The next step is to remove the handle knobs. If there’s a decorative cover on top of each knob, pry it off with a screwdriver or prying tool. Underneath, there will be a screw that mounts the handle to the stem. You can usually unscrew this with your hand, but if it’s stuck, try wiggling and prying it free with your screwdriver. You may also need to use penetrating oil to loosen it. Once the handle is removed, you’ll be able to see what the problem is. If the cam and packing are leaking, you can tighten them with needle-nose pliers. The adjusting ring can also be tightened, but if it’s the one that leaks, you’ll need to replace it.

After removing the handles and screw, you should be able to remove the adjusting nut. You can do this by placing a spanner wrench over the nut, or you can unscrew it with your hands. The adjusting nut is usually the first part of the faucet that starts to leak. It can be a little tricky to replace, but once you’ve done it, the problem should be fixed.

You may need to reinstall the washer or O-ring, and if you have a ceramic-disk cylinder, you’ll need to replace the neoprene seals or clean them. You can do this yourself by using a plumber’s wrench or you can purchase a faucet repair kit.

While repairing your faucet, make sure you keep something over the drain to stop old and new parts from falling down the drain. Small faucet parts are hard to hold, and they can easily slip through a hole or get lost down the drain. Also, it’s a good idea to have a towel or old T-shirt handy so you can wipe down your hands and the working parts of the faucet.
